Ever see the impressive reflective floors.. the ones that you copy, and paste the primitives and rotate them 180 degrees, and tie the floor too a func_wall.
But you still can't get the floor to look real?.. Try this:
Make two floors, 1unit thick, and put one on top of each other.
Next tie the floor on top to a func_wall.. with the properties set to this:
Render Mode::::Color
FX Amount::::::70
This makes the floor a solid color, black, yet almost invisible.
Now for the floor on the bottom, make sure it has a neat texture, perhaps of squares.
Set this func_wall to this:
RenderMode::::Texture
FX Amount::::: 90
Now this will let you view the texture, only slightly invisible.
When done, you have a shiny floor that doesn't appear fullbright.
Happy Mapping!
